Don’t Let the Lights Go Out: Defend Against EMP (No, this isn't about tinfoil hats!)

Heritage; The Foundry "...an EMP can occur when a nuclear weapon is detonated high in the atmosphere above the Earth. The resulting explosion interacts with the Earth’s magnetic fields, sending a pulse, or current, throughout all electrical systems. Nearly everything we depend on from day to day would be affected. Imagine a world without computers, ATMS, cell phones, water systems, the internet, ambulances and even cars. The U.S. would essentially be knocked back to the 19th century. "
